Max's father is very close to her, the two attending sports events together. He's presented as a very loving father figure. He doesn't seem to be as concerned as Max's mother about Blackwell.
In a text message regarding Max's eighteenth birthday, he says that she is an adult now but still their little girl and she shouldn't blow the money her parents sent her at once.
He is concerned about the threat he gets from an unknown number in episode four and messages Max about it.
In another text message to Max in the alternative timeline where Max has won the Everyday Heroes Photo Contest, he points out that Max is an adult now and can tell her mother that she doesn't need to be too worried regarding the arrest of Jefferson and Nathan.
